I really like the non-mechanical simple bias tape makers that Clover has .. simple .. effective .. and inexpensive .. they come in many sizes. They do have them at JoAnn's.

This is what I use and I have been very pleased with them. BrendaK
I have used these with the special adhesive tape that is made for the tool and have found the very best hint I ever recieved was STARCHING! If the bias strip is starched before you feed it through the gadget the fold really stays in place. I use these bias strips for vines and celtic patterns outlines. For quilt edges I always use the double fold WOF strips. Best of luck!
